What is Treated Wood Waste?

Treated Wood Waste (TWW) comes from wood that has been treated with chemical preservatives.  These chemicals help protect the wood from insect attack and fungal decay while it is being used as a building material such as fence posts, sill plates, guardrails, deck supports, etc.  The California Department of Toxic Substances Control (DTSC) defines treated wood waste (TWW) as wood that has been treated with chemical preservatives.  The chemical preservatives are classified as hazardous and pose a risk to human health and the environment.  Please see the document produced by DTSC in December of 2020.

Until December 31, 2020 there were regulations that allowed treated wood waste to be handled with alternative management standards that resulted in more options for generators to safely dispose of such wastes.  However, effective January 1, 2021 all of the alternative management standards expired and treated wood waste managed in California will have to be stored and manifested as HAZARDOUS WASTE and transported to class I hazardous waste landfills for disposal.  See the DTSC website for complete information.

Bee Green Recycling & Supply, LLC has never allowed the disposal of TWW at any of our facilities.  TWW will continue to be rejected at our scale house and on the tipping pad. Any customers discovered trying to dispose of the material at our facility will be asked to keep the treated wood on their vehicle and be instructed to seek guidance from the DTSC about proper disposal options for the hazardous materials.  Repeat offenders may be turned into the DTSC for illegal management of the hazardous materials.
